Research ArticleOpen accessIn the abstractScale Formation Due to Water Injection in Malaysian Sandstone CoresAmer Badr Bin Merdhah, Abu Azam Mohd YassinProblem statement: Scale deposition is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Approach: This study was conducted to investigate the permeability reduction caused by deposition of calcium, strontium and barium sulphates in sandstone cores from mixing of injected Malaysian sea waters (Angsi and Barton) and formation water … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,624 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Quercetin on Diabetes-Induced Alteration in CYP3A Activity and Bioavailability of Pioglitazone in RatsSudhir Niranjan Umathe, Pankaj Vinod Dixit, Jignesh Manubhai Vaghasiya, Nishant Sudhir JainProblem statement: Quercetin-a common bioflavonoid, is present in herbal preparations consumed by diabetic patients along with routine anti-diabetic agents. We recently showed that quercetin increases the bioavailability of pioglitazone in non-diabetic rats. Thus, present study investigated whether this pharmacokinetic interaction is also evident in diabetic animals, especially because diabetic subjects have altered gastrointestinal (GI) function and CYP3A activity. Approach: The … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 7,818 accessesView PDF Cite
